Objectives: To describe the value of high resolution computed tomography scan (HRCT scan) in post traumatic hearing loss.
Method: HRCT scan of the temporal bone in millimetric cut with axial and coronal views was performed.
Results: CT scan confirmed pneumolabyrinth with intact stapes depressed deeply into the vestibule. Surgical exploration was performed and the stapes was gently removed from the vestibule.
Conclusion: CT scan confirmed the diagnosis and studied the stapes integrity. Hearing deteriorated postoperatively is increased in case of stapes fracture. When a luxation of the stapes into the vestibule is suspected, it is important to determine how deeply and whether it is fractured. When such a case is encountered, high resolution CT scan of the temporal bone must be performed to confirm the diagnosis and to confirm integrity of the stapes.

Besides classical stapedotomy, reverse stapedotomy has been used for many years in the management of otosclerosis. Our study aims to investigate whether reversing the surgical steps in stapedotomy impacts vestibular function and hearing improvement. A cohort of 123 patients underwent either classic or reverse stapedotomy procedures utilizing a fiber-optic argon laser.

Article Synopsis
- The study explored traumatic pneumolabyrinth caused by tympanic membrane perforation, focusing on clinical manifestations, treatment approaches, and patient outcomes.
- Clinical data from 3 unique cases (2015-2021) were analyzed alongside 22 additional cases from PubMed that detailed pneumolabyrinth due to tympanic injuries.
- Results indicated that all patients had TM perforations, with most suffering from vertigo, but hearing recovery did not correlate with vertigo severity; treatment effectiveness varied, with some patients improving while others did not.

We report a rare case of traumatic stapes luxation into the vestibule. A 31-year-old female visited an emergency room with sudden onset of vertigo and conductive hearing loss after accidental penetrating injury to the right ear. Temporal bone computed tomography detected pneumolabyrinth, with a shade of whole intact stapes in the vestibule.

Background: The aim of this study was to evaluate whether surgeons´ experience and perioperative single-shot antibiotic prophylaxis affect outcome of patients undergoing stapes surgery.
Patients And Methods: We retrospectively evaluated audiological outcomes and postoperative complications of 538 consecutive patients who underwent stapes surgery at a single tertiary referral center between 1990 and 2017. Effects of different clinical variables, including single-shot antibiotic prophylaxis and surgeons' experience on outcome were assessed.
